Abstract (en)
[origin: WO2021050330A1] A corrugated protective textile sleeve has a flexible, tubular wall of woven warp yams, extending lengthwise along a longitudinal axis between opposite ends of the wall, and weft yams, extending generally transversely to the warp yams. At least some of the weft yams are activatable weft yam to shrink in length and at least some the weft yams, adjacent the activatable weft yam, are substantially non-activatable weft yam. The substantially non- activatable weft yam form crests, having a first diameter, spaced axially from one another and the activatable weft yams, upon being activated and shrunken, form valleys, having a second diameter less than the first diameter, with at least some of the valleys extending between the crests to form the wall having a corrugated contour.
